Sakai is way out in the suburbs on the way to Kansai airport
Rihga has a number of hotels in the Osaka area, including the
Rihga Royal Hotel Yotsubashi not far from the area you are aiming for. Prices are quite reasonable, especially for singles. Not quite a Nikko, but not as expensive either.
Check these
maps for hotel locations by area.
Also, clicking on 'Access route' in
this link gives you an idea of hotel locations if their sites only indicate a nearby station. The map is not to scale, but the Rihga in Sakai would be on the orange Nankai-sen on the way to KIX.
